Unfortunately, the latest (0.2) version of Ocemp’s GUI no longer includes the draw method, and provides no direct way to tell when the display has changed. Usage of Lamina to display GUIs in OpenGL mode relies on the ‘dirty rectangle’ list to know when to do the slow operation of regenerating the textures.

So continue using v 0.1, if you need Lamina to interface with an OpenGL display. Marcus has suggested he plans to support the v 0.1 code for a while.
